SLINGF ATTACHMENT FOR HAY-FORKS.

963,121. Patented July 5, 1910.

Serial No. 526,220.

Specification of Letters Patent. Application led November 4, 1909.

the drawings by letter, A represents a hay sling, such as I employ inconnection with the horse fork, the fork used being' of any of the wellknown forms of horse hay forks such as are' in common use. The slingconsists of two ropes B and B, each of which is doubled and has its endssecured to metallic keepers D and E, the body portion of the rope beingpassed through eyelets or keepers b and b carried by the cleats C. Thekeeper E is in the form of a latch or locking device capable of beingreleased by a downward pull of a tripping rope which may be snapped orotherwise connected wit-h a ring E2 at the lower end of a trigger ropeE3.

J is a horse fork which may be of any of the forms of construction whichare commonly used but, in the present instance, I have shown a fork ofthe type known commonly as a harpoou fork provided with the side arms Jand pivoted barb points J which points are adapted to be thrown in wardout of engagement with the load carried by the fork by the tripping ofthe toggle joint connection at a point adjacent to the upper end of thefork, this tripping being accomplished by a downward pull to the tripcord K.

S designates a metallic casing divided by vertical partitions into threecompartments within which are journaled three independent pulleys overwhich are passed strands of the loop rope T, which rope has connected atits ends suitable hooks H adapted to be en gaged by the upper ends ofthe sling ropes Pivoted within the central compartment of the casing Sis a cam pawl R adapted to engage the rope upon the pulley P and holdthe same against backward movement, as will be readily understood. Thecasing S is bolted at its upper end to a cross bar S, the opposite endsof which bar are extended upward to form the hooks M, M to the rear ofwhich hooks is provided a hook Q opening upward, said hook beingdesigned to receive the coiled free end of sling attachment rope T whennot in use.

O is a pulley, the casing of which has swivel connection with the crossbar N at the upper end of the hay fork over which pulley travels therope O which is used in raising the fork with its load.

From the foregoing description of the construction of my forkattachment, its operation will be readily understood. In loading hay orgrain upon a wagon, the sling is 'o all 'whom it may concern:

Be it known that I, JEROME A. Cross, a citizen of the United States,residing at Fultonville, in the county of Montgomery and State of NewYork, have invented certain new and useful Improvements in SlingAttachments for Hay-Forks; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

This invention relates to certain new and useful improvementsv in slingattachments for hay forks and it has for its object the provision of asimple, inexpensive and eiiicient attachment whereby means is providedfor retaining the free ends of the ropes when not in use and readilydetaching the same for use when desired.

To these ends and to such others as the invention may pertain the sameconsists in the novel construction, peculiar arrangement, combinationand adaptation of parts, all as will be hereinafter described, shown inthe accompanying drawings and then specifically delined in the appendedclaims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification and in which r- Figure l is a perspective view of a haysling of ordinary construct-ion, the same being shown as used inconnection with a horse fork and with my improved attachment shown inposition for use. Fig. 2v is an enlarged detail in perspective of thesuspending hooks and rope holding hook which forms the subject matter ofthe present invention, and Fig. 3 is a sectional detail of the hook andits connections.

By the use of the horse fork, difficulty is experienced in removing thelast of the hay from the wagon after the bulk of the load has beenremoved and it is customary to remove the latter part of the load by theuse of a hay fork. The sling which I have shown is designed especiallyfor use in connection with a horse fork with the viewl of providingmeans whereby the entire load may be removed without the necessity ofthe use of hand forks as is common.

Reference now being had to the details of opened out upon the wagon bedand the hay or grain is loaded thereon. Upon arriving at the barn or thepoint at which the hay is to be removed from the wagon, the horse forkis operated in the usual way for removing the upper part of the load,after which the sling ropes B are brought upward so that the sling willembrace that portion of the load still remaining upon the wagon and thelooped upper ends of the sling ropes are hooked over the hooks H carriedat the lower ends of the loop rope T passing over the pulleys containedin the casing S, the

hooks M being hooked over the bar N of tho horse fork. The trip rope Kis disengaged.

from its connection with the tripper rope K of the fork and the snapupon the ends of the rope is engaged with the ring t at the end oi' thesling trigger rope Ef. The bottom portion of the load being thusembraced within the sling is hoisted from the wagon by the meansemployed in hoisting loads carried by the fork.

I-Iaving thus described my invention, what I claim to be new and desireto secure by Letters Patent is l. In combination with a pulley blockcasing divided into a plurality of compartments, a series of pulleysjournaled one in each of said compartments, a hook fastened to saidcasing and adapted to engage over a hay ork to support thc casing, arope passing about ,two of said pulleys, tackle blocks having pulleysabout which said rope passes and provided with hooks for engagement onewith each end of a sling, a third pulley mounted in one oi"- thecompartments of said casing and about which a hoisting portion oi" therope passes, and means for holding the purchase of said hoisting rope.

2. In combination with a pulley block casing divided into a plurality ofcompartments, a series of pulleys journaled one in each oit' saidcompartments, a hook fastened to said casing and adapted to engage overa hay fork to support the casing, a rope passing about two of saidpulleys, tackle blocks having pulleys about which said rope passes andprovided with hooks for engagement one with each end of a sling, a thirdpulley mounted in one of the compartments of said casing and about whicha hoisting portion the rope passes, a pivotal gravity pawl mounted inthe compartment in which said third pulley is journaled and adapted toengage the hoisting portion of the rope to hold the purchase.

In testimony whereof I hereunto aix my signature in the presence of twowitnesses.
